Revive GEMDOS for lisa

Gemdos was known as atari ST operating system (to be precise, TOS is GEM + atari port of GEMDOS). This OS was primarily developped on Lisa and VME10 platform.

Caldera did buy parts of Digital research Inc and released old sources to public.

This hack aims to run gemdos and gem on lisa hardware.

One interesting archive is oemkit.zip

It's a kind of patch over gemdos build environment.

The interesting file is bootflop.bat:

REM THIS BATCH FILE CREATES A BOOTABLE 3.5 DISKETTE
REM IT IS ASSUMED THAT YOU HAVE ALREADY FORMATTED THE DISKETTE WITH FORMAT.PRG
REM IF YOU WISH TO ABORT, ENTER APPLE C KEYS
REM IF YOU WISH TO CONTINUE, ENTER THE ENTER KEY

Now the result (in "intergalactic" exclusivity ;) )

You may now start gemdos in emulators (both IDLE and lisaem). Not tested yet on real hardware but... It'll work...

Now the tool itself

This tool uses a non free FAT12 implementation that is part of miniC by Dave Dunfield (www.dunfield.com). Since this hack is open source and non commercial, I suppose it does not hurt the conditions of use...
